Siri isn't lame because of the lack of frontier LLM. Siri is a massive failure of simply coding it to do obvious things, which is a UX failure, which is ironic given Apple's reputation as the UX leaders. I guess it is a low bar considering the competition of MS and Goog.

Over the last 6 years, I have fully bought into the ecosystem and it constantly dissapoints me. I invite the UX team to spend a few days watching me struggle with their fragmented ecosystem. But I warn them to not let me get started on AppleTV (the streaming app), where the enshitification takes the crown over all of their competitors. They seem to have jumped the shark past the give the consumer great value stage.
